SUMMARY:Motion-Driven Neural Optimizer for Prophylactic Braces Made by Dis

  (University of Manchester)\n\nJoint injuries, and their long-term consequ
 ences, present a substantial global health burden. Wearable prophylactic b
 races are an attractive potential solution to reduce the incidence of join
 t injuries by limiting joint movements that are related to injury risk. Gi
 ven human motion and ground reaction forces, we present a computational fr
 amework that enables the design of personalized braces by optimizing the d
 istribution of microstructures and elasticity. As varied brace designs yie
 ld different reaction forces that influence kinematics and kinetics analys
 is outcomes, the optimization process is formulated as a differentiable en
 d-to-end pipeline in which the design domain of microstructure distributio
 n is parameterized onto a neural network. The optimized distribution of mi
 crostructures is obtained via a self-learning process to determine the net
 work coefficients according to a carefully designed set of losses and the 
 integrated biomechanical and physical analyses. Since knees and ankles are
  the most commonly injured joints, we demonstrate the effectiveness of our
  pipeline by designing, fabricating, and testing prophylactic braces for t
 he knee and ankle to prevent potentially harmful joint movements.\n\nRegis
